Answer:

So basically, since the formula is 2(l × w), we will do:

(Length) 2/5 + 2/5 (the same thing as multiplying it by two) which equals 4/5.

Then we do the same for the width:

(Width) 1/5 + 1/5 (also the same thing as multiplying by two) to get 2/5.

Now we just add both fractions: 4/5 + 2/5 = 1 1/5

So the answer is C.
